The needs of neutrino physics call for the next generation, higher-power, megawatt and multi-MW-class superbeams facilities. Elements of the LBNF/DUNE Phase II, a world leading neutrino experiment,
were discussed at Snowmass'21. There is a broad array of accelerator and detector technologies and expertise to design and construct a 2.4 MW beam power upgrade of the Fermilab accelerator complex for Neutrino Frontier studies [1]}, expand the volume of Liquid Argon detectors by 20 ktons, and build a new neutrino near-detector on the Fermilab site.
